Review on Optimized Concrete Anchorage: Arrow Shed AK100 by Kofi Wills

Not sure if these anchors really deserve 5 stars but I can say I had no excitement installing these anchors . My Arrow barn sits on a slab that I filled with Quikrete 4000 PSI concrete. I would say it takes about 30 to 40 days to dry before attempting to build a canopy on top of the slab. My experience is very positive. I prepared for bit issues based on previous reviews and fitted a quality masonry bit just in case something went wrong. Instead, I was pleasantly surprised when I drilled through all 12 corner holes with ease. I had no problems with the included anchor bolts or screws. Everything was up to Arrow's standards - with a little persuasion it went well.
